In general, it is best to pick a small part of functionality to add, write the tests, complete the implementation, and check that in. In this case, the moving of existing interfaces (and renamings/extraction) has wide-spread implications. If you do not mind, I am going to complete that part today. So by Tuesday, you should be able to work on the SPI itself and add the new functionality without having to worry about breaking things other than the RI and perhaps any extensions that might already be dependent on the RI (there shouldn't be any yet that I know of).

The tests are always a good way to make sure your implementation is sound and that you did not break any existing functionality. These tests do depend a bit more on the RI, but if you use an IDE that can help with the refactoring between RI and the JSR-299 API, problems should be minimal. > > (3) Given that the work involves repackaging/renaming, a lot of > things > are going to break in dependent modules.

I think it might be OK to work on webbeans extensions afterwards. As I stated above, though, I should have all the repackaging/renaming done, and the rest of the work should just be "new" SPI interfaces extracted from the RI. That should not have any impact on dependent modules. We do not usually write code in other modules dependent directly on the RI. > > (4) What is the timetable for reaching the next release milestone > with > these changes, i.e. will the next webbeans release target this draft > of the spec, and if so, what is its target date?

This needs to be done before the end of June, but Pete should have a more exact date for you.

Another team member is working on tck-audit.xml and should be done soon. I would not write any new TCK tests right now without knowing what the assertion numbers are going to be. Check back later after you have more of the SPI done and the TCK is more in-line with the current spec.
